While driving a car, we make a full faith on Car brakes. We may not think very often about the failure of Car brakes but brake plays a major role in our Car journey. It protects us from the collision and plays an important part in our defense. But What are the causes of Car Brake Failure?
What is a Car Braking system?
Unlike the Train braking system Car braking system is very strong. A train has Air braking system, whereas the car uses a hydraulic braking system. A hydraulic brake system is an arrangement of a braking mechanism which uses brake fluid to transfer pressure from the controlling mechanism to the braking mechanism. This fluid is made up of glycol ethers or diethylene glycol. When we press braking pedal with a force, it compresses the brake fluid by master piston cylinder. This will transfer the pressure to disc-caliper pistons and to the rear wheel-cylinder pistons that makes car wheels to stop.
What are conditions for loss of control on brake?
All the mechanical components have a limited time period. Brake system of a car is also based on mechanical components. Although with all good conditions, brakes have a limited lifespan. After a time period, they stop working. Sometimes there can be a manufacturing problem or defect.
The function of your brakes depends on several steps working properly. The most common reasons are
- Due to Leak in Brake lines: The Fluid will not flow correctly if there is a leak in the brake line. The fluid leak and mixed in the air due to which there is not enough fluid left that create pressure on the piston to stop the wheel.
- Due to loose of Bleed valve: A bleed screw is used to create a temporary opening in an in a closed hydraulic system, which facilitates the removal of air or another substance from the system by way of pressure and density differences.
- Leak in Master Cylinders: When you press the brake pedal, it pushes on the primary piston through a linkage. This Pressure builds in the cylinder and this will further press brake lines. This pressure between both the piston makes the fluid to move which acts as a break.
- Faulty ABS unit: ABS pump is a very common failure for all Vauxhall Corsa vehicles built between 2006 and 2014, the common fault is complete lack of braking effort to the front left brake caliper because brake fluid is reaching the left side front brake caliper so it is impossible to bleed the left side front brake.
- Worn Brake Pads: A brake pad is a thin block that presses on to the disc in a disc brake.
Can Car Brake fail Often?
No, In a survey of America, We get to know the brake failures only cause about 5% of the car crashes in the US every year. There are 5.6 million car crashes in America every year, So crashes by brake failure is 300,000 per year.
What are the signs your Break system can fail to work?
- If by pushing breaks it sounds noisy then we should take it to the shop and have them checked.
- Brakes feel spongy, in that case, the car pulls to one side when you brake.
- You should also pay attention to how the pedal feels. If it is sinking at the floor or if the pedal seems stuck in a lower position.
- Keep an eye out for fluid leaking from under your car. If it is a brake fluid then it loses the pressure in your brake lines.
Failure of a braking system is a very serious issue in your car. You must maintain your car and take your car into the shop the moment you think you may have a problem with your brakes. if your car is older, as it may not have some of the backup safety instruments.
